Abstract

A cyclonic separating apparatus includes a separating chamber, an inlet communicating with the separating chamber and an outlet formed by a conduit communicating with an interior portion of the separating chamber and having a longitudinal axis, wherein a single planar baffle projects radially inwardly from an interior surface of the conduit towards the longitudinal axis. The presence of the baffle in the outlet has the effect of reducing noise generated by the apparatus when in use and also improves pressure recovery.
